What Are Fuels And Lubricants?

Fuel is material with one type of energy which can be transformed into another usable energy. A common example is potential energy being converted into kinetic energy, (as heat and mechanical work). In many cases this is just something that will burn.

Lubricant is a substance based on heavy liquid hydrocarbons used to reduce friction in an engine or machine.

Lubricants are an essential part of modern machinery. Everything from computer hard disk drives to the Airbus A380 requires lubrication of its moving parts.

A lubricant (colloquially, lube, although this may also refer to personal lubricants) is a substance (usually a liquid) introduced between two moving surfaces to reduce the friction and wear between them. A lubricant provides a protective film which allows for two touching surfaces to be separated, thus lessening the friction between them.

The word fuels is defined as any materials which are capable of releasing energy when their chemical or physical structures are changed or converted. Fuels release their energy either through chemical means, such as burning, or through nuclear means, such as nuclear fission or nuclear fusion. An important property of all useful fuels is that the energy released by them can be stored and released only when they are needed. In that way, the release of energy can be controlled in such a way that this energy can be harnessed to produce work.

The word lubricants is defined as such substances which are usually in the liquid state of matter. Lubricants are colloquially known as lubes. They are introduced between the surfaces of two moving surfaces. Lubricants reduce the friction and wear-and tear between them. Lubricants provide protective layers of film which allow for two touching surfaces to be separated. This lessens the friction between them. Lubricants are an essential part of all modern-day machinery.
